liftUpward-acting force on an aircraft wing or airfoil. An aircraft in flight experiences an upward lift force, as well as the thrust of the engine, the force of its own weight, and a drag force. The lift force arises because the speed at which the displaced air moves over the top of the airfoil (and over the top of the attached boundary layer) is greater than the speed at which it moves over the bottom and because the pressure acting on the airfoil from below is therefore greater than the pressure from above. lift 1. a. Brit a platform, compartment, or cage raised or lowered in a vertical shaft to transport persons or goods in a building 2. the force required to lift an object 3. a. the component of the aerodynamic forces acting on a wing, etc., at right angles to the airflow b. the upward force exerted by the gas in a balloon, airship, etc. 4.
